Abstract
In this paper, a detailed theoretical analysis of the
second harmonic generation (SHG) efficiency versus the polarization ratio
and the crystal lengths of CsLiB6O10 (CLBO) in the phase matching
using a computer simulation are presented. The efficiency of SHG has been up
to 80% when the pumped radiation is of a plane wave. The efficiency is 65%
and 80% as the pumped wave is of Gaussian beam in type I and type II,
respectively. It is useful result that the phase matching of type II be
perfectly adopted in the SHG experiment of CLBO.
